12V 100Ah LiFePO4 Battery Group 31 Lithium Battery With Built-in 100A BMS, 1.28kWh Up to 15000 Deep Cycles Rechargeable Battery for RV, Automotive Replacement Batteries

This Grnoe 12.8v 100Ah LifePo4 battery is a great battery at a great price. The company also is very responsive to anything that pops up as well. I had purchased another brand that worked well with my pontoon boat and I was looking to purchase another over the holidays. I discovered this battery at $20 less (without a charger that the other one offers). Since I had already purchased the special LifePo4 battery charger, I decided to try this. It arrived packaged very well and in great shape. I especially like that this seems to have better quality batteries in it since it has a higher life cycle of up to 15,000 times versus around 10,000 for most other 100Ah LifePo4 batteries. I also appreciate that the BMS has a documented max cut off current of 300 amps versus 200 on most others. It is also nice to know that it comes with a 3-year warranty which offers a lot of peace of mind. It is tempting to replace my car battery with one of these but since we are in the upper midwest, we frequently go below -4F which is where this and any other LifePo4 battery will stop sending power. If you are in the market for a 100Ah LifePo4 battery, you definitely need to consider those offered by Grnoe.

So far they are working very well

I upgraded my RV batteries and charger for these high quality batteries. LiPo is definitely worth it if you need new batteries.

4 stars because of what happened, 5 stars because of the seller. The first one I bought I got on sale, put the correct type of charger on it, and it went from saying 0% to 100% in about 5 minutes. I figured it was the charger since it was also new. 6 weeks later I get the trolling motor that it is for. It worked for 2 minutes, then the battery was reading dead. Tried to charge but the automatic charger wouldn't do anything. Hooked charger to other batteries, both LiFeP04 and Lead acid since that charger can do both, and it started to charge them all and quickly read full like it should. Contacted the seller since it was past the Amazon return period. Bessie was awesome. Every reply was with a couple hours, in ENGLISH, and very helpful. I answered her questions, and got a new battery and prepaid return label. New battery came in and worked amazingly well over the weekend. If anyone is debating changing from lead acid to lifep04, DO IT AND BUY FROM HERE! Less weight, and I used spot lock on a 24v terrova about a half mile below a power dam for 6 hours and still had over 50% battery. The trolley ran at 3-4 out of 10 the whole time.Awesome seller, they took care of me. One use on the battery and it's awesome too.

Shipped fast and packed intelligently with lots of foam padding. The terminal screws are included. The fit is good and length is fine as long as you are only connecting one lug. I purchased two of these and both have operated perfectly. Both came in just over 13v. The instructions go about telling you how to drop test them and offer a warranty. The price is right ( $108 shipped ) when they have them in stock. As of today they are now around $175! At that price I would look elsewhere.Update: Still Running Strong 💪 Although the company did not follow through with their promised sales promotion. Because of this and the shifty switcheroo sales tactics they used; I will not be using this company for any future purchases.

31 is a big battery

Great product the quality is good. Using the battery was very easy, it is a little heavy but that’s to be expected.

Batteries look great and work well, unfortunately I only recieved 3 of the 4 Batteries I ordered. The company replied back right away that the shipment got separated during transit and assured it was still in route. The missing battery was delivered a few days later.
